类

类	描述
`BKPasscodeField`	一个自定义控件，符合 `UIKeyInput`。当它成为第一个响应者时，键盘将显示以输入密码。
`BKPasscodeInputView`	一个支持数字或普通（ASCII）密码的视图。此视图可以显示标题、消息和错误消息。您可以覆盖静态方法来自定义标签的外观。
`BKShiftingPasscodeInputView`	一个在两个 `BKPasscodeInputView` 之间进行转换的视图。您可以前后移动密码视图。
`BKPasscodeViewController`	一个支持创建、更改和验证密码的视图控制器。
`BKPasscodeLockScreenManager`	一个在应用进入后台状态时显示锁定屏幕的管理器。您可以使用 `activateWithDelegate:` 方法激活。
`BKTouchIDManager`	一个管理器，用于保存、加载和删除密钥链项目。它将密码保存到密钥链，并且需要指纹才能访问项目。

示例

呈现密码视图控制器

BKPasscodeViewController *viewController = [[BKPasscodeViewController alloc] initWithNibName:nil bundle:nil];
viewController.delegate = self;
viewController.type = BKPasscodeViewControllerNewPasscodeType;
// viewController.type = BKPasscodeViewControllerChangePasscodeType;    // for change
// viewController.type = BKPasscodeViewControllerCheckPasscodeType;   // for authentication

viewController.passcodeStyle = BKPasscodeInputViewNumericPasscodeStyle;
// viewController.passcodeStyle = BKPasscodeInputViewNormalPasscodeStyle;    // for ASCII style passcode.

// To supports Touch ID feature, set BKTouchIDManager instance to view controller.
// It only supports iOS 8 or greater.
viewController.touchIDManager = [[BKTouchIDManager alloc] initWithKeychainServiceName:@"<# your keychain service name #>"];
viewController.touchIDManager.promptText = @"Scan fingerprint to authenticate";   // You can set prompt text.

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self presentViewController:navController animated:YES completion:nil];

在没有呈现密码视图控制器的情况下使用 Touch ID 进行验证

BKPasscodeViewController *viewController = [[BKPasscodeViewController alloc] initWithNibName:nil bundle:nil];
viewController.delegate = self;
viewController.type = BKPasscodeViewControllerCheckPasscodeType;   // for authentication
viewController.passcodeStyle = BKPasscodeInputViewNumericPasscodeStyle;

// To supports Touch ID feature, set BKTouchIDManager instance to view controller.
// It only supports iOS 8 or greater.
viewController.touchIDManager = [[BKTouchIDManager alloc] initWithKeychainServiceName:@"<# your keychain service name #>"];
viewController.touchIDManager.promptText = @"Scan fingerprint to authenticate";   // You can set prompt text.

// Show Touch ID user interface
[viewController startTouchIDAuthenticationIfPossible:^(BOOL prompted) {

  // If Touch ID is unavailable or disabled, present passcode view controller for manual input.
  if (NO == prompted) {
    UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
    [self presentViewController:navController animated:YES completion:nil];
  }
}];

显示锁定屏幕

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  // ...

  [[BKPasscodeLockScreenManager sharedManager] setDelegate:self];

  // ...
  return YES;
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
  // ...
  // show passcode view controller when enter background. Screen will be obscured from here.
  [[BKPasscodeLockScreenManager sharedManager] showLockScreen:NO];
}

- (BOOL)lockScreenManagerShouldShowLockScreen:(BKPasscodeLockScreenManager *)aManager
{
  return YES;   // return NO if you don't want to present lock screen.
}

- (UIViewController *)lockScreenManagerPasscodeViewController:(BKPasscodeLockScreenManager *)aManager
{
  BKPasscodeViewController *viewController = [[BKPasscodeViewController alloc] initWithNibName:nil bundle:nil];
  viewController.type = BKPasscodeViewControllerCheckPasscodeType;
  viewController.delegate = <# set delegate to authenticate passcode #>;

  UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
  return navController;
}
